记录一下Mac上面安装桌面版K8S

去官网下载docker-desktop for mac 链接 并安装

about docker desktop

我的资源配置

注意K8S的版本 v1.15.5

下载k8s的相关组

由于墙太厚了，自动更新不成功，我们用阿里云提供的镜像，创建一个可执行文件load_images.sh，下面是文件内容

注意版本号 KUBE_VERSION 是否与上面的k8s版本号一致，不一致改成一致的就可以了

##!/bin/bash

set -e
KUBE_VERSION=v1.15.5
KUBE_DASHBOARD_VERSION=v1.10.1
KUBE_PAUSE_VERSION=3.1
ETCD_VERSION=3.3.10
COREDNS_VERSION=1.3.1
GCR_URL=k8s.gcr.io
ALIYUN_URL=registry.cn-hangzhou.aliyuncs.com/google_containers

# get images
images=(kube-proxy:${KUBE_VERSION}
kube-scheduler:${KUBE_VERSION}
kube-controller-manager:${KUBE_VERSION}
kube-apiserver:${KUBE_VERSION}
pause:${KUBE_PAUSE_VERSION}
etcd:${ETCD_VERSION}
coredns:${COREDNS_VERSION}
kubernetes-dashboard-amd64:${KUBE_DASHBOARD_VERSION})

for imageName in ${images[@]} ; do
docker pull $ALIYUN_URL/$imageName
docker tag $ALIYUN_URL/$imageName $GCR_URL/$imageName
docker rmi $ALIYUN_URL/$imageName
done

docker images

运行文件等待执行完成

$ ./load_images.sh

打勾重启看看有没有全部running

命令行看看版本，出现client 和server 就表示安装成功

由于我是升级上来的，安装期间遇到很多坑，最后一怒之下做了这个操作，按上面步骤再走一遍终于成功（此间凄凉何人诉）

k8s web ui配置（kubernetes-dashboard）

还是由于墙的原因，我们在本地创建一个yaml文件webui.yaml
